July is usually a busy month but it historically starts to thin out by the first or second week in August.
There are a few reasons. One is that the weather in North and America and Europe is normally good in August and September - so folks don't need to spend a lot of money flying to the tropics when it's sunny in their own back yard.
Secondly, yes, hurricane season - not so much because of the risk of hurricanes, which is extremely low this far south, but because so many insurance companies require that yachts remain further south.
Thirdly, because a very large number of yachts head back to the USA or Europe for the summer months, typically leaving these parts in April and returning in November.
TimeHonoured - my favourite time of year to sail in the Grenadines is peak hurricane season (hurricanes apart, of course). The winds in the summer months are lighter, with correspondingly comfortable seas; between the tropical waves, the weather can be fabulous with 60-mile visibility, flat waters and lots of sunshine. I've been in the Cays in mid-September and been one of only two yachts there, and the only one in Salt Whistle Bay.
